Description

A kind of conductive spinning product and preparation method thereof
Technical field
The present invention relates to the preparation of conductive material, more particularly, relate to a kind of conductive spinning product and preparation method thereof.
Background technology
Known fiber, yarn, fabric and the film that has dual mode to obtain to conduct electricity namely adopts in blended yarn or composite yarn the mode that embeds metal wire or other conductor wire or conductive material, and on the surface of textile substrate the mode of coated with conductive material.Comprise metal, metal oxide, metal nanoparticle, conducting polymer and carbon-based material in the conductive material for the manufacture of the fiber, yarn, fabric and the film that conduct electricity.
For first kind of way, several production methods known in the state of the art.PCT International Application No. WO 93/24689 is exactly to adopt this mode to use the textile fabric of identical or different type to make the method for composite yarn, in these textile fabrics twisted metal wire, silver-plated or the gold-plated copper of annealing or the stainless steel of annealing, its diameter is between 0.008mm to 0.05mm.At twisted behind this composite yarn/fabric, metal wire is located substantially on being in contact with one another on the y direction between the zone of each textile fabric.Another kind of similarly method is described in European patent document EP-A-0 644 283.Wherein, metal wire and braided wire are being brought to the mutual twisted of a time-out.Paper (D.Marculescu et al.Proceedings of the IEEE 2003,91,1995 and S.Jung et al.ISSCC 2003/Session 22/TD:EmbeddedTechnologies/Paper 22.1) fabric of having integrated metal wire is disclosed.The patent No. is that 3987613 United States Patent (USP), European patent document EP-A-0 250 and the patent No. are to disclose some other spinning method in 6032450 the United States Patent (USP).These methods are widely applied, and are very tight because of braided wire and the combination between the metal wire of the composite yarn for preparing by embedding grammar.But, these methods are Shortcomings also, metal wire has born suitable mechanical prestress to a certain extent, and composite yarn is relatively hard to fracture easily, may there be certain risk in this, so that composite yarn/fabric further separating during the processing again, and when these metal thighs by solder bond together the time, the weaving carrier structure of peripheral region possibility is destroyed before welding procedure or in the process.Carbon-based material, for example carbon fiber, graphite and CNT also can directly be spun in conductive yarn/fabric.But not only still there is limitation in this on cost, and its electric conductivity is still poor than metal when soldered connection.
Another kind of mode namely covers layer of metal, CNT or conducting polymer at conventional fibre, spun yarn subsequently, be a kind of make conductive yarn more economically and fruitful mode.In the yarn of these productions, people focus on the yarn of paying close attention to metal coating.The patent No. is that 4522889 United States Patent (USP) discloses a kind of conduction aromatic polyamides cloth that has applied copper and mickel by chemical plating.But, do not obtain roughly uniformly metal coating, particularly at the yarn crossovers place of pre-textile fabric.And equally in the patent No. is 5302415 United States Patent (USP) not coated filament has appearred also.The patent No. is that 5935706 United States Patent (USP) has been described with copper and come technique to various aromatic polyamide fibers metallings.The technique of the disclosure has used 80% to 90% sulfuric acid solution to modify the surface of aromatic polyamide fibers.This modification is controlled fiber degradation by depolymerization and is realized, thereby provides the site for the deposition of the sensitizer that promotes the electrolytic metal deposition.Yet, use 80% to 90% sulfuric acid solution in these patents, this will destroy all natural fabrics, for example, cotton, silk and wool, on the other hand, the copper that deposits by wet chemical method means that this deposition is located immediately at polymer surfaces, and this will cause the combination between metal and the aromatic polyamide fibers surface very weak.When making the weaving electronic device, the metallized fiber of this weakness can not bear tough woven or knitting.
Recently, the people such as Zheng develops a kind of technology of making polyelectrolyte-bridging metal-coating cotton yarn.In the method, by surperficial Atom Transfer Radical Polymerization (SI-ATRP) at the thinner polyelectrolyte layer of cotton yarn surface graft.The conducting metal that comprises copper and mickel deposits on the polyelectrolyte layer by ion-exchange and chemical deposition subsequently.The conductive sponge that so makes is very durable in machinery and washing test.This work has convincingly demonstrated polyelectrolyte and can be used as a kind of very effective bridge layer between soft base and the hard metal coating, producing the very firm hierarchy with good pliability and electric conductivity.Yet SI-ATRP technique exists some not enough, has seriously hindered large-scale production and commercialization.At first, it is very responsive to oxygen, need to carry out nitrogen protection.Therefore, SI-ATRP is very difficult to be applied in the extensive manufacturing, particularly in textile industry.Secondly, the chemical conversion rate from the monomer to the polymer is low-down, so that most of monomer all is wasted.The 3rd, reaction speed is slow, may need 24 hours.In addition, present technology can only be used for preparing conductive fabric in specific or limited substrate.Therefore, demand urgently developing a kind of can be generally with and the high technology of output make conductive fabric, this technology can be used to leniently making these polyelectrolyte-bridging metal-coating cotton yarn and fabric and be applicable to follow-up reel-to-reel technique in dissimilar substrates under the condition.

Wherein textile substrate can adopt: cotton, silk, wool, nylon, polyester, spandex, Lycra, aramid fiber or elastomer.The electrolyte tack coat can be PMETAC.Metal coating can be copper coating, nickel coating, copper nickel coating or silver coating.
The below describes the concrete steps of the preparation method of conductive spinning product of the present invention.In this embodiment, the present invention adopts based on the padding of in-situ polymerization-drying-curing process and prepares poly-[2-(methacryloxypropyl) ethyl-trimethyl salmiac] (PMETAC) coating cotton yarn.Use subsequently precious metal ion such as Pd 2+Have chemical deposition metallic on the cotton yarn of polymer coating, producing conductive yarn.This technique is as shown in Fig. 1 a.In a model experiment, at first cotton yarn was immersed in the anhydrous toluene solution of the 7-octenyl trichlorosilane contain 2～20mM 1 to 6 hours, so that cellulosic hydroxyl and silane molecule generation condensation reaction.Then use other dry toluene and ethanol cleaning down, with silane and the products molecule of removing unnecessary Physical Absorption.Clean at last the cotton yarn of silanization with clear water, and then in 40～60 ℃ vacuum dry 2～4 hours.Subsequently, the immobilized cotton yarn of silane is immersed in contains 3.11～31.1g METAC and 2.46～24.6mg K 2S 2O 8The aqueous solution of 50mL in 5～15 minutes, and then at 2～5kg/cm 2Pressure under pad.Through twice immersion with pad, the cotton yarn that makes heats 1～3 hour to carry out polymerization at 70-120 ℃ in baking box again.In radical polymerization process, two keys of silane can by free radical open with [2-(methacryloxypropyl) ethyl-trimethyl salmiac] (METAC) polymerization so that the PMETAC on cotton yarn surface constantly increases.(the NH that will have at last, the cotton yarn immersion 5～10mM of PMETAC coating 4) 2PdCl 4In the aqueous solution 0.5～1 hour, PdCl wherein 4 2-Group is because to QA +Having higher compatibility is fixed on the polymer by ion-exchange.The palladium group has effective catalytic action to chemical depositing copper, nickel and silver.After using 4 * 200ml deionized water rinsing, yarn is dipped in copper or the nickel chemical plating fluid 15～60 minutes at last, or in the silver chemical plating bath in 35-40 ℃ of reaction 30-90 minute, subsequently water flushing and drying up.Gained has the conductive sponge fabric of copper coating, nickel coating or silver coating respectively shown in Fig. 1 b, 1c and 1d.The copper chemical plating fluid consists of 12g/L NaOH, 13g/L CuSO 45H 2O, 29g/L potassium sodium tartrate and 9.5mL/L HCHO; The nickel chemical plating fluid consists of 40g/L Ni 2SO 45H 2O, 20g/L natrium citricum, 10g/L lactic acid and 1g/L dimethylamino borine.Also can adopt the method alternately to soak the conductive sponge fabric that preparation has the copper nickel coating by yarn at copper chemical plating fluid and nickel chemical plating fluid.The silver chemical plating bath is at first prepared 1g/L AgNO3 solution, drips an amount of 34%wt ammoniacal liquor and obtains silver ammino solution, then itself and equal-volume 5g/L sodium tartrate potassium solution is mixed.
Fig. 2 and Fig. 3 show respectively Fourier transform infrared spectroscopy (FTIR) and x-ray photoelectron spectroscopy (XPS) characterization result, confirm that manufacturing process of the present invention has successfully prepared required structure.In Fig. 2,1728cm -1The peak at place is because the carbonyl of PMETAC shows successfully to have applied PMETAC on cotton yarn.The XPS presentation of results of Fig. 3 the details of whole process.Article 2, the success that strong Si2p and Si 2s signal show the silane fixation procedure on the line, dipping subsequently-dry-solidifying process after, the cotton yarn that produces shows because obvious Cl and the n-signal that PMETAC produces at the 3rd line, this representative on the cotton yarn surface successfully grafting PMETAC.After ion-exchange, on the 4th line, strong 3d signal has appearred, and it can promote copper or nickel to be plated on the cotton yarn surface effectively, respectively shown in the 5th line and the 6th line.The metal signal that this is obvious and strong shows to have homogeneous and fine and close copper and mickel coating on the cotton yarn surface.The cotton yarn and continuing that Fig. 4 a, 4b, 4c and 4d be respectively cotton yarn, silanization cotton yarn, have the coating of PMETAC is covered with the scanning electronic microscope schematic diagram of the cotton yarn of copper coating, and the figure that inserts among Fig. 4 d is the profile that is covered with the cotton yarn of copper coating.As seen from the figure, the not obviously difference of the configuration of surface of the cotton fiber of silanization and the cotton fiber with PMETAC coating and raw-material configuration of surface, this shows that process does not cause any adverse effect to the outward appearance of cotton yarn.
By the time of control chemical plating, the electric conductivity of the cotton yarn with copper coating that so makes is adjustable.In general, electroplating time is long so that electric conductivity is high.We are subsequently by scanning electron microscopic observation ELD reaction.As time goes on, the yarn expansion that progressively becomes, and copper layer thickness increases, thus produce electrical conductivity (such as Fig. 5).Soak after 60 minutes, copper layer thickness rises to above 250nm, and the resistance of cotton yarn drops to 45 Ω/square metre (Fig. 5), uses thereby can be used as electric wire.Yet after 90 minutes ELD or longer time, thickness and the resistance variations of copper layer are little, and this shows when the saturated stage of stable development occurs in about 60 minutes and soaks.
Except cotton, this method also can be used for making conductive fiber or fabric in various types of materials, such as silk fabrics, wool, nylon, polyester, spandex, Lycra and aramid fiber, the conductive material that shown in Fig. 6 a and Fig. 6 b, is respectively raw material and makes through the inventive method.Different from cotton is, before manufacture process began, the fiber of other materials or fabric must adopt the oxygen plasma activation, and it can produce activity hydroxy to fix the two keys that contain silane by with chlorosilane (cholorosilane) condensation reaction occuring.All metal coating textiless take various materials as substrate that so make show good electric conductivity and durability.
Slightly make an amendment, the method can also be used to modify the elastomeric material with draftability, and for example fiber, film and the rubber made of dimethyl silicone polymer (PDMS) to prepare stretchable conductor, is used in stretchable electronic device as wire.The process that produces PMETAC at the PDMS substrate surface is the same with the process of the PET of foregoing description and Lycra etc., and difference a little is that chemical plating process subsequently is to implement when the elastomer of PMETAC modification is stretched to specific degree of strain.After the chemical plating process was finished, elastomer was relaxed, thereby formed from the teeth outwards regular flexing, simultaneously metal level still keep complete and can not produce any breakage or or peel off, shown in Fig. 7 a and 7b.When metallized elastomer was used as electric wire in integrated circuit, it can bear and stretch or crooked, because its flexing can be straightened the strain that provides larger, bore less pressure and metal level self is actual when applying external force, shown in Fig. 7 c-f.The metalized elastomeric that so makes has good electric property, it in addition can be elongated 300%, as shown in Fig. 7 g and the 7H.These results show that the method has larger potentiality when preparation can stretch electronic product.
The present invention is described according to specific embodiment, but it will be understood by those skilled in the art that when not breaking away from the scope of the invention, can carry out various variations and be equal to replacement.In addition, for adapting to specific occasion or the material of the technology of the present invention, can carry out many modifications and not break away from its protection domain the present invention.Therefore, the present invention is not limited to specific embodiment disclosed herein, and comprises that all drop into the embodiment of claim protection domain.
